Understanding the Equation of a Circle

The equation of a circle in standard form is given by (xβˆ’h)2+(yβˆ’k)2=r2{(x-h)^2+(y-k)^2=r^2}, where (h,k){(h,k)} represents the coordinates of the center of the circle, and r{r} is the radius. In the given equation (x+9)2+(yβˆ’6)2=102{(x+9)^2+(y-6)^2=10^2}, we can identify the values of h{h}, k{k}, and r{r}.

Identifying the Center of the Circle

To find the center of the circle, we need to identify the values of h{h} and k{k} in the equation. In the given equation, the value of h{h} is βˆ’9{-9}, and the value of k{k} is 6{6}. Therefore, the center of the circle is represented by the coordinates (βˆ’9,6){(-9, 6)}.

Analyzing the Options

Let's analyze the options given in the problem:

  • A. (βˆ’9,6){(-9, 6)}
  • B. (βˆ’6,9){(-6, 9)}
  • C. (6,βˆ’9){(6, -9)}
  • D. (9,βˆ’6){(9, -6)}

Conclusion

Based on the analysis, the correct answer is option A. (βˆ’9,6){(-9, 6)}. This is because the value of h{h} in the equation is βˆ’9{-9}, and the value of k{k} is 6{6}, which corresponds to the coordinates (βˆ’9,6){(-9, 6)}.

Final Answer

The final answer is (βˆ’9,6){(-9, 6)}.
